Alstroemeria plant named ‘Tesnava’

ABSTRACT

A new and distinct cultivar of  Alstroemeria  plant named ‘Tesnava’, characterized by its compact and uniformly mounding plant habit; sturdy and strong plants; moderately vigorous growth habit; purple and white bi-colored flowers with short pedicels; and good garden performance.

Botanical designation: Alstroemeria hybrida.

Cultivar denomination: ‘TESNAVA’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Alstroemeria plant, botanically known as Alstroemeria hybrida, grown typically as a potted garden Alstroemeria, and hereinafter referred to by the name ‘Tesnava’.

The new Alstroemeria plant is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program is to create new potted garden Alstroemeria plants that flower continuously and have attractive leaf and flower coloration.

The new Alstroemeria plant originated from a cross-pollination made by the Inventor in De Kwakel, The Netherlands in April, 2006, of a proprietary Alstroemeria hybrida selection identified as code number Pa920, not patented, as the female, or seed, parent with a proprietary Alstroemeria hybrida selection identified as code number Pa1819, not patented, as the male, or pollen, parent. The new Alstroemeria plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in De Kwakel, The Netherlands in April, 2007.

Asexual reproduction of the new Alstroemeria plant by root divisions in a controlled greenhouse environment in. De Kwakel, The Netherlands since May, 2007 has shown that the unique features of this new Alstroemeria plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Alstroemeria have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environment conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Tesnava’. These characteristics in combination distinguish ‘Tesnava’ as a new and distinct Alstroemeria plant:

-   -   1. Compact and uniformly mounding plant habit.     -   2. Sturdy and strong plants; moderately vigorous growth habit.     -   3. Purple and white bi-colored flowers with short pedicels.     -   4. Good garden performance.

Plants of the new Alstroemeria can be compared to plants of the female parent selection. Plants of the new Alstroemeria differ from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Alstroemeria are shorter than plants of the         female parent selection.     -   2. Plants of the new Alstroemeria and the female parent         selection differ in flower bud color as plants of the female         patent selection have lavender green-colored flower buds.     -   3. Plants of the new Alstroemeria and the female parent         selection differ in flower color as plants of the female patent         selection have pink and white bi-colored flowers.     -   4. Plants of the new Alstroemeria have shorter pedicels than         plants of the female parent selection.

Plants of the new Alstroemeria can be compared to plants of the male parent selection. Plants of the new Alstroemeria differ from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Alstroemeria are shorter than plants of the         male parent selection.     -   2. Plants of the new Alstroemeria and the male parent selection         differ in flower bud color as plants of the male patent         selection have light pinkish green-colored flower buds.     -   3. Plants of the new Alstroemeria and the male parent selection         differ in flower color as plants of the male patent selection         have white and blushed pink-colored flowers.

Plants of the new Alstroemeria can be compared to plants of the Alstroemeria hybrida ‘Staprivane’ disclosed in U.S. Plant Pat. No. 14,131. In side-by-side comparisons, plants of the new Alstroemeria differed primarily from plants of ‘Staprivane’ in the following characteristics:

-   -   1. Plants of the new Alstroemeria and ‘Staprivane’ differed in         flower bud color as plants of ‘Staprivane’ had purple-colored         flower buds.     -   2. Plants of the new Alstroemeria and ‘Staprivane’ differed in         flower color as plants of ‘Staprivane’ had purple and yellow         bi-colored flowers.     -   3. Plants of the new Alstroemeria had shorter pedicels than         plants of ‘Staprivane’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Alstroemeria plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Alstroemeria plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Tesnava’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants of the new Alstroemeria grown in 4.6-liter containers during the winter in a glass-covered greenhouse in De Kwakel, The Netherlands. During the production of the plants, day and night temperatures ranged from 18° C. to 22° C. Plants were 15 weeks old when the photograph and description were taken.
